Description

TECHNICAL FIELD

The disclosure relates to a service search technology of a Personal Network (PN), in particular to a method and a device for searching a personal network service.

BACKGROUND

The Personal Network is a network formed by connecting Personal Network Equipments (PNEs) owned by a person, such as portable digital products, intelligent household appliances, mobile terminals and the like, so that these equipments are enabled to be connected to an external network through any equipment with network access; wherein these equipments which provide wireless or wired external network access are called as Personal Network Gateways (PN Gateways), and the PNE can access to the service and content provided by the external network through the PN Gateway or provide service and content to the external network.
When there is a need to use the service content of the external network, the PNE can select the service interested by a user after accessing to a service list provided by the external network and looking up such information as a service content brief introduction, a service information fee and the like. However, as far as immense amount of personal network services are considered, it is very inconvenient to look up the service list on each page of the PNE. The other way is that the PNE initiates a service corresponding to keyword search, for example, for the keyword search on the existing Internet, a server also possibly returns lots of service information but some information is not suitable for the PNE to use. It is because that the difference between the PNEs is great, and such difference is embodied in: operating system, display screen, keyboard, processing capability, file format and the like, which are not as normalized as a computer used by the user; consequently, by aiming at different PNEs, lots of service contents are required for content adaptation. However, while initiating a search, the user will not consider what format of content his PNE requires, and the keyword initiated by the user generally is only involved in the service content, for example, the user can initiate the search by inputting a name of a song or a name of a singer and wait for a returned search result, but lots of the search results are returned and are not always satisfied with a use requirement of the PNE. In this way, it is obviously difficult to select the suitable service content therefrom as there are lots of search results; furthermore, it is possible to find many contents that are inadaptable to the PNE.
It can be seen from the above that, when the PNE searches the service content in an immense number of personal network service contents currently, a search speed of the service content is not rapid enough and the search result is not exact enough.

Preferably, the device is further configured to provide the PNE with a search result returned by performing a search of the service content by the personal network server according to the primary keyword and the auxiliary keyword.
It needs to be noted that, the device of the disclosure can be internally arranged in a PNE, a PN Gateway or a PN server; of course, the device can further serve as an equipment independent of the PNE, the PN Gateway and the personal network server.
In addition, the device can extract the configuration information corresponding to the PNE from configuration information corresponding to each equipment in a PN maintained by the device, and generate the corresponding auxiliary keyword according to the configuration information extracted and the primary keyword used for searching the service content by the PNE; of course, the device further can directly generate the corresponding auxiliary keyword to the configuration information provided when the PNE transmits the primary keyword.
Based on the idea of the disclosure, another method for searching a personal network service provided by the disclosure includes: obtaining a search result generated by performing a search by a personal network server according to a keyword used for searching a service content by a PNE; and generating a filtering condition according to configuration information of the PNE, filtering the search result generated by the personal network server, and providing the search result filtered to the PNE. Wherein, the configuration information of the PNE includes at least one of parameters: capability information, state information, location information and service usage statistic information of the PNE, user preference information and the like.
The disclosure further provides a device corresponding to the realizing method, and the device includes: a search result filtering unit configured to generate, when obtaining a search result generated by performing a search by a personal network server according to a keyword used for searching a service content by a PNE, a filtering condition according to configuration information of the PNE, filter the search result generated by the personal network server, and provide the search result filtered to the PNE.
It needs to be noted that, the device can be internally arranged in the PNE, the PN Gateway or the personal network server; of course, the device can further serve as an equipment independent of the PNE, the PN Gateway and the personal network server.
In addition, the device can extract configuration information corresponding to the PNE from configuration information corresponding to each equipment in a PN maintained by the device, generate the corresponding filtering condition according to the configuration information extracted; of course, the device further can generate the corresponding filtering condition according to the configuration information provided when the PNE transmits the keyword.
The above searching method based on the generation of the auxiliary keyword can be used in combination with the method based on the search result filtering; that is, two parts as follows are included: generating the auxiliary keyword according to the configuration information of the PNE and providing the auxiliary keyword to the personal network server for performing the search of the service content; and generating the filtering condition according to the configuration information of the PNE to filter the search result returned by the personal network server. The specific operations of the two parts are referred to the two methods provided in the disclosure respectively and here will not repeat them. The above various methods for searching the personal network service will further described in detail in combination with the specific embodiments hereinafter.
A method for searching a personal network service provided by a first embodiment of the disclosure as shown in Fig. 1 mainly includes the following steps.
Step 101, a PNE transmits a primary keyword used for searching a service content to a PN Gateway.
When needing to perform a search of a personal network service content, a user transmits the primary keyword used for searching the service content to the PN Gateway which the user is located at through the PNE. For example, when the user needs to search a song, the user can input the name of the song and the singer's name serving as the primary keyword on the PNE, and transmits the primary keyword to the PN Gateway.
Step 102, the PN Gateway generates an auxiliary keyword according to configuration information of the PNE, and transmits the primary keyword received and the auxiliary keyword generated to a personal network server.
When receiving the primary keyword for searching the service content transmitted by the PNE, the PN Gateway extracts the configuration information corresponding to the PNE from the configuration information corresponding to each equipment in the PN maintained by the PN Gateway, generates a corresponding auxiliary keyword according to the extracted configuration information, and transmits the primary keyword received and the auxiliary keyword generated to the personal network server.
It needs to be noted that, when the PNE will registere while joining to the PN; and during the process, the PN Gateway can collect the configuration information of the PNE; during a networking process of the PNE, the state of the PNE will be changed; and during the process, the PN Gateway can collect the configuration information of the PNE updated. The PN Gateway stores the configuration information of each PNE collected. When the PNE needs to search the service content, the PN Gateway can fully make use of the information stored and extract relevant parameters to generate the auxiliary keyword. The auxiliary keyword limits the received keywords so that the rapid search can be realized and the searching accuracy can be improved.
For example, during a process of searching an audio and video, the auxiliary keyword of the video and audio format is added so that the searched content is more suitable for the PNE; when searching a game, the search of an on-line game or an off-line game can be limited according to the state statistic information of the PNE; when searching a restaurant place, the nearby restaurant places satisfying the user can be searched according to the geographic location information of the PNE and the flavor set according to the user preference; and when searching discount promotion information, the discount promotion type that is visited usually by the PNE is searched according to the historic service use statistic information of the PNE.
Step 103, the PN Gateway receives a search result returned by performing a search of the service content by the personal network server according to the primary keyword and the auxiliary keyword, and forwards the search result to the PNE.
For example, if the PNE only supports to play a music of a mp3 format, the PN Gateway will limit the mp3 format according to the parameter of the PNE when generating the auxiliary keyword, so that the service content searched by the personal network server will not include a song of the other format (such as wma); while downloading the video, the auxiliary keyword generated by the PN Gateway according to the capability parameter of the PNE will limit the resolution of the video, so that the personal network server will not search the content format beyond play capability of the PNE.
Corresponding to the method for searching the personal network service as shown in Fig. 1, the disclosure further provides a device for searching a personal network service, and the device can be arranged in the PN Gateway and be also used as the external equipment of the PN Gateway. The structure of the device can be referred to Fig. 2; Fig. 2 is a structural diagram of the system for searching the personal network service that is composed of a PNE 10, a PN Gateway 20 and a persona network server 30. The device for searching the personal network service according to the disclosure is arranged in the PN Gateway 20.
The device includes an equipment management unit 21, a keyword generation unit 22 and a keyword transmission unit 23. Wherein, the equipment management unit 21 is configured to maintain configuration information corresponding to each equipment in a PN; the keyword generation unit 22 is configured to extract configuration information corresponding to the PNE 10 from the equipment management unit 21 when receiving a primary keyword used for searching a service content transmitted by the PNE 10, and generate an auxiliary keyword according to the configuration information extracted; the keyword transmission unit 23 is configured to transmit the primary keyword received and the auxiliary keyword generated to the personal network server 30; the personal network server 30 is configured to return the search result to the PN Gateway 20 when obtaining a search result by searching the service content according to the primary keyword and the auxiliary keyword; and the PN Gateway 20 forwards the search result to the PNE 10.
Furthermore, the equipment management unit 21 is further configured to: obtain the configuration information of the PNE 10 when the PNE 10 joins and registers to the PN, and update the configuration information of the PNE 10 during a networking process of the PNE 10.
Also, in order to realize that the PNE rapidly and efficiently searchs the personal network service, the method for searching the personal network service in a second embodiment of the disclosure mainly includes the following idea: a PNE sends a keyword to a PN Gateway; the PN Gateway forwards the keyword to a personal network server; the personal network server returns a search result to the PN Gateway; the PN Gateway generates a filtering condition according to configuration information of the PNE, filters the search result received by using the filtering condition and transmits the search result filtered to the PNE.
Based on the above idea, the method for searching the personal network service provided by the second embodiment of the disclosure as shown in Fig. 3 mainly includes the following steps.
Step 301, a PNE transmits a keyword used for searching a service content to a PN Gateway.
Step 302, the PN Gateway transmits the keyword to a personal network server and receives a search result returned by the personal network server.
Step 303, the PN Gateway generates a filtering condition according to configuration information of the PNE, filters the search result received and transmits the search result filtered to the PNE.
For example, if the PNE only supports to play the music of the mp3 format, the PN Gateway will limit the mp3 format according to the parameter of the PNE when generating the filtering condition, so that when filtering the search result returned by the personal network server, a song of other format (such as wma) will be filtered away, and thus only the songs of the mp3 format are remained in the search result filtered; while downloading the video, the filtering condition generated by the PN Gateway based on the capability parameter of the PNE will limit the resolution of the video, so that while filtering the search result returned by the personal network server, the resolution of the video is limited, and the content format beyond the play capability of the PNE does not exist in the search result filtered.
Corresponding to the method for searching the personal network service as shown in Fig. 3, the disclosure further provides a device for searching a personal network service; the device can be arranged in the PN Gateway and be also used as an external equipment of the PN Gateway. The structure of the device can be referred to Fig. 4; Fig. 4 is a structural diagram of the system for searching the personal network service that is composed of a PNE 10, a PN Gateway 20 and a persona network server 30. The device for searching the personal network service according to the disclosure is arranged in the PN Gateway 20, and is configured to forward the keyword used for searching the service content transmitted by the PNE to the personal network server and receive the search result returned by the personal network server.
The device includes an equipment management unit 21 and a search result filtering unit 24. Wherein, the equipment management unit 21 is configured to maintain configuration information corresponding to each equipment in the PN; and the search result filtering unit 24 is configured to extract configuration information corresponding to the PNE 10 from the equipment management unit 21, generate a filtering condition according to the configuration information extracted, filter a search result returned by the personal network server, and transmit the search result filtered to the PNE 10.
In addition, the equipment management unit 21 is further configured to obtain, when the PNE 10 joins and registers to the PN, the configuration information of the PNE 10, and update the configuration information of the PNE 10 during a networking process of the PNE 10.
In conclusion, by means of the disclosure, the PNE can rapidly and efficiently search the service content interested by the user through the PN Gateway, so that the search speed and search accuracy of the personal network service content are improved.
In addition, the searching method based on the generation of the auxiliary keyword as shown in Fig. 1 can be used in combination with the method based on the filtering of the search result as shown in Fig. 3; and in an embodiment of the combined use, the portion based on the generation of the auxiliary keyword can be referred to the flow as shown in Fig. 1, the portion based on the filtering of the search result can be referred to the flow as shown in Fig. 3, and here will not repeat them.
The above are only the preferred embodiments of the disclosure, but are not intended to limit the scope of protection of the disclosure.
